Hi,

I have just started learning lammps. I prepared an input for MoS2, and I set REBO potential for pair _coeff and pair_style, but I gave this error:

{pair_style rebo

pair_coeff * * MoS.REBO.set5b M S

ERROR: Incorrect args for pair coefficients (src/MANYBODY/pair_airebo.cpp:198)

Last command: pair_coeff * * MoS.REBO.set5b M S}

would you help me to solve this problem?

Thanks
